Question

The product of two rational number is 5/18.If one of them is-3/20, find the other.

Answer 1

Let the other no. be X

Now,

according to question

$(x) \times \frac{ - 3}{20} = \frac{5}{18}$

$x = \frac{5}{18} \times ( \frac{ - 20}{3} )$

$x = \frac{5}{9} \times ( \frac{ - 10}{3} )$

$x = \frac{ - 50}{27}$

Hence, the other no. is (-50/27)
